Measurement of SMM included arm index (arm SMM / height2), leg index (leg SMM / height2) and appendicular index (appendicular SMM / height2). The prognosis of LC with sarcopenia was then analyzed using Kaplan–Meier analysis. Appendicular SMM / height2 tended to be lower in LC than in DM, but the difference GDC 0068 was not significant (men: LC, 7.37 ± 1.06 kg/m2; DM, 7.52 ± 0.92 kg/m2; women: LC, 6.31 ± 0.88 kg/m2; DM, 6.48 ± 1.12 kg/m2). In particular, arm index was significantly lower in LC (men: LC, 1.87 ± 0.32 kg/m2; DM, 2.00 ± 0.32 kg/m2; P < 0.01; women: LC, 1.50 ± 0.31 kg/m2; DM, 1.63 ± 0.37 kg/m2; P < 0.05). In this study, sarcopenia

was defined based on the result of the PF-01367338 solubility dmso arm index. Values less than −1 standard deviation from the mean values in the DM group, namely, less than 1.7 kg/m2 in men and 1.2 kg/m2 in women, were considered to be indicative of sarcopenia. Comparison of patient background characteristics between the groups with and without sarcopenia showed a significantly greater proportion of men in the group with sarcopenia (23 men, seven women) than in the group without sarcopenia (57 men, 50 women; P < 0.05), but no significant differences in

mean age (68 ± 9 vs 66 ± 9 years). Child–Pugh score was higher (men, 6.9 ± 1.7 vs 6.5 ± 1.7; women, 8.1 ± 2.7 vs 6.7 ± 1.6) and hepatic functional reserve was lower in LC with than in LC without sarcopenia. In addition, analysis of prognosis with stratification for arm index showed that prognosis was significantly poorer in the arm index subgroup with lower values (Fig. 1, P < 0.05). Sarcopenia may coexist in LC, particularly in LC with decreased hepatic functional reserve, and measurement of arm SMM can be useful in evaluation. LC patients should be monitored for sarcopenia

using arm SMM, because nutritional therapy can readily improve the prognosis. “
“We read with great interest the article by McNally et al.,1 上海皓元 who reported the involvement of a seasonally varying environmental agent in the etiology of primary biliary cirrhosis (PBC), and who have reported previously that a transient environmental agent may be involved in the etiology using a space-time clustering method among cases of PBC in a defined geographical population of northeast England.2 A combination of genetic predisposition and environmental factors are thought to contribute the etiology of PBC.3 As environmental factors, certain bacterial and viral infections, including Escherichia coli, mycobacteria, and a retrovirus, are reported to be involved.4 To date, however, no specific virus has been implicated in the pathogenesis, although cases of PBC tend to cluster within areas. Herpes simplex virus (HSV) is a hepatotropic virus, but it is an uncommon cause of hepatitis in immunocompetent adults.
